Abstract

The invention discloses a backlight module and a liquid crystal display device. The backlight module comprises a back plate, a light bar, a first optical film, a rubber frame and an adhesive layer. The corresponding optical film is fixed on the opposite side of the light bar through the adhesive layer, so that the heating variation of the corresponding optical film is concentrated on one side of the light bar, and the fixing reliability of the corresponding optical film in the vehicle-mounted backlight module and the narrow bezel of the backlight module can be realized; and the problems of eliminating or weakening the bright edge of the edge of the backlight module and the firefly effect are solved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to the field of backlight technology, and in particular to a backlight module and a liquid crystal display device. Background technique [0002] With the development of vehicle-mounted display technology, the requirements for the appearance of vehicle-mounted backlight modules are getting higher and higher, tending to be larger and narrower. Paste double-sided tape on it, and fix the corresponding optical film on one side in the long direction of the backlight module; the optical film is assembled and fixed based on the fixed side, and the expansion and contraction space of the optical film is reserved on the other side. [0003] Due to the relatively strict reliability requirements of the backlight module for vehicles, it is generally used to design a boss on the light guide plate to fix the corresponding optical film; in view of the narrow frame limit of the backlight m...
